Abstract

A system for operating a valve comprising a motor shaft driven by a motor; a first cam with a profile mounted to the motor shaft, a second cam with a profile mounted to the motor shaft; a non-contact sensor proximate to the first cam; and a valve actuator. The valve actuator follows the profile of the second cam. A selected position of the valve actuator may be set by activating the motor to a position determined by sensing the first cam profile by the non-contact sensor.
